I found it interesting that they sent me details of the research study and told me how they valued my opinion, then said I couldn't participate because I wasn't in America.

I drafted an email in reply, questioned if they did value my opinion and wondered if they even cared that they were making it obvious they didn't by sending it out to me in the first place. I mean, they have all my details, they know know I live in Scotland.

Anyway, my email pinged back with a message "This is a no reply email."
